TYPEWRITNG- MACHINE.

Application f'iled, March 5, 1921.

To all 'whom t may concern:

known that l, Jnssn A. B. SMITH. a citizen of the United States, residing in Stamfordi in the county of Fairfield and State of ilonnecticut, have invented certain new and useful improvements in Typewriting Machines, of which the following is a specification.

This invention relates to paper-carrying devices of typewriting machines, and is shown applied to an Underwood front-strike machine.

@ne of the objects of the invention is to facilitate the typing of short work or billsheets calling for entries upon only two or three lines, as in the case of gas bills. Vhere but a few entries are to be made, and a large number of work or bill-sheets are to be typed, it is not satisfactory to insert the sheets from the rear and adjust them to typing position, as these operations consume a great` deal of time in proportion to the amount of actual typing. The present invention simplifies the introduction of the work-sheets and their adjustment to the printing position.

In carrying out the present invention, the work-sheets are inserted at the front of the platen bottom end Jforemost. Their upper ends are collated upon a table adjustably mounted on the machinein such position that, when a work-sheet is aligned at its top and side vedges on gages carried 'by the table. the work-sheet will be properly positioned at the printing point. Since the headings (the distance from the upper edge to the first line to be typed) of various types of work-sheets vary in length, means are provided for rapidly adjusting the'end gage of the collating table forwardly or rearwardly of the machine, and hence toward or away from the upper edge of the worksheet.- The adjusting means is capable of being moved rapidly through distances equal to full line-spaces or to fractions of a linespace. The collating table is capable of being swung by means of a finger-piece to an inactive position.

The work-sheets having been adjusted in position, means are provided whereby said sheets may be typed upon one, two or three lines. For this purpose, the end .gage of the collating table is mounted upon a slidable plate adapted to be moved upwardly and held in position at line-space intervals,

the sheets, which are held to the table by spring-ngers, being moved up by hand to the end gage in its raised positions. By the above-described means, a simple, rapid, and eiiicient method of typing short work-sheets is obtained.

Other features and advantages will hereinafter appear.

In the accompanying drawings,

Figure 1 is a front view of a machine. with the invention applied thereto, only the necessary co-operating parts ofthe machine being shown. 4

Figure 2 is an end view, partly sectioned, of the device shown in Figure 1, the collating table being in its extreme forward position.

Figure 3 is an end view of the device shown in Figure l, the collating table being in its eXtreme rearward position.

In the Underwood standard typewriting machine, a platen 10 is fixed upon an axle 11 journaled in the end walls 12 of a shiftable platen-frame forming part of the usual typewriter carriage.

A collating table, indicated .generally at 20, is mounted on the platen-frame by means of a rod 21 supported `on the end walls in the following manner: The ends of rod 21 are seated in sockets in the collars 22 and 23 of end members or journals 24 and 25. The journals are of the same diameter as the rod 21, and are mounted in the U-shaped supports 26 and 27 fixed onthe end walls 12 of the platen-frame. The journals 24 and 25 are each provided with a longitudinal groove, the two grooves being in alignment, and detents 28 and 29, 'vertically slidable in Vsupports 26 and 27 are pressed against said members 24 and 25 and adapted to lodge in the grooves to hold said members, and hence the rod 21, firmly in position.

The rod 21 is also provided with a longitudinal groove 21EL in which are adapted to seat spring-pressed detents 30 carried by U-shaped supports 31 in a similar manner tov those of supports 26 and 27. Supports 31 are carried by brackets 32 fixed to the rear wall 33 of the table by screws 34. Since the position of the collating table varies, as will be described later, the spring-pressed detents will not lodge in the groove in rod 21 unless the rod is turned through thesame angle as the table at each change of position. For this purpose, the rod 21 may be rotated in thecollarsi22 and k23 on the end members 24 and 25 vby loosening screws 35, which fasten the rod 21 in the colla-rs. When the rod has been adjusted to proper position, the screwsare tightened, and the end members and rod l21 again move as aV unit. finger-piece 36 is iixed by screw 37 to one end of an end member, and, by actuating this linger-piece, the rod 21 and the collating table may be rotated forwardly to effective position or rearwardly to ineffective position.

Al work-sheet may be inserted at the front of the platen bottom end foremost until-the first line to be typed is at the printing point, the upper end of the sheet resting upon the collating table. The latter may be moved forwardly or rearwardly until an upper end gage 46 comes in Acontact with the leading edge of the work-sheet. The table is then fixed in position.l and thereafter work-sheets of the same variety inserted at the front of the machine need only have their leading edges positioned in contact with the upper p, is fixed to the y rear'rbar *ter'sunl in the topVV plate, theV oountersunk end'gage 40, and the sheets will be properly positioned to type the first line. The worksheetsf may be gaged at one side edge by a side-edge gage .50 on table 20. The means enablingk the collat-ing table to be moved forwardly andrearwardly. and to be fixed .in adjusted position arenow 'to be described.

The end supports 26 and 27, carrying the journals 24 and 25 and rod 21 with its collating table, are fixed to base-blocks 41 and 42, respectively, through which are threaded screws 43 and 44.* The lower ends of the screws operate in forwardly and rearwardly extending slots 45 in plates 46 fixed by screws 47 to the tops of the platen-frame end walls. The lower ends of the screws 43 and 44gare threaded into nuts 48, larger than the slot-s 45 to prevent withdrawal of the nuts.V Shoulders 49 on screws 43 and 44 may b ev screwed down to press upon the upper surface ofthe base-blocks 41 and 42, to holdV the lat-ter firmly in position against theplates 46. By unscrewing screws 43 and 44, theblocks 41 and 42 are free to move forwardly or rearwardly, carrying the collatingtable nearer or further from the leading edge of the work-sheet.

here'more than Vone line is to be typed, means must be provided for suitably gaging ,j vsuch sheets hat line-space intervals. The

line-spacing accomplished by mounting the -end gage 40-on a slidable plate 60 between a; top plate 62 ofthe collating table and a vbott'im or rea-r bar 61. The plate 62 61'by screws 63 coun portion of plate62 providing clearance be.- tween the top plate and the rear bar Vfor the sli'dable lplate '60,., The latter has cut-out portions'64 adapted to clear the screws 63 `when is movedfupwardly For moving the slidable plate upwardly, a linger-piece 65 fixed thereto is moved toward the left. Pins 66 fixed to the top plate 62 project into cam-slots 67 provided with dwells 68 at their ends. `When finger-piece 65 is moved toward the left, plate 60 rides upwardly on pins 66. A spring 7 0, fixed to the rear bar, is provided with a pin 71 adapted to project through an opening in said rear bar and press against 4the slidable plate. Three openings 7 2, 73, and 74 are provided in plate 60 corresponding to the lowest and two raised positions of the plate, each raised position being one line-space position above the previous position. The pin 71, lodging in the openings 72, 73, and 74, will hold the plate 60 in each position, and, in addition` the pins 66, riding on dwells 68, will hold the plate 60 firmly in lowest and highest positions. Vhei-e more than three lilies are to be typed, longer cam-slots 67 and more openings, similar to 72, 73, and 74, may be provided. Spring-iingers 75, attached to the rear plate and bent over to contact with the front plate, aid in holding` the work-sheets in position. The loops of the springs are sufficiently large not to interfere with thev upward movement of the slidable plate.

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.
